My Tangie photoperiods small leaves are curling upwards around the edges. Anybody have a reason for this? It's the only one of the 4 exhibiting symptoms like this and only one of my autos of the 8 did the same thing. Is it too much or too little water? Not enough airflow?Week 9

I’m referring to the last 3 pictures in week 7. Those leaves are near the bottom of the plant, not getting enough light. I thought they’d yellow gracefully before finally crisping up and fall off. But these are dying gruesomely. Is this normal, or a nute issue? What’re those?Week 7

Are rust spots a concern for harvest?Hi! Rust spots appearing on fan leaves - Week 9 Autoflower - 5th week of flower. I'm hesitant to add anything to the soil so close to harvest. I'm using Gaia Green Organic dry amendments. Is this normal and part of 'fade' process? Will this damage yield or potency? 6.3PHWeek 9
